Lets say you have run a site for years and all of a sudden the site is not getting any traffic, or next to none. Do you ever give up on a site when it loses traffic and you can't seem to gain new traffic? I have never given up on a site, but if a site of mine is doing low numbers, I try to see why and fix it. If I can't I may sell the site off to someone else to take on. What about you?
